Hordeum secalinum is regionally assessed as Least Concern as it is widely distributed in northern, middle, east, southeastern and southwestern Europe. However, although it is widely distributed in many parts of its range, there are reported population declines in some countries and it is considered to be threatened in Germany. There is currently no knowledge available about the threats to this species; therefore, research is needed to identify the cause of these population declines. Population and habitat monitoring is also recommended at national level.
|Range Description:||H. secalinum is native to northern, middle, east, southeastern and southwestern Europe, as well as to Macaronesia and northern Africa (Valdés and Scholz; with contributions from Raab-Straube and Parolly 2009, USDA, ARS, National Genetic Resources Progam 2010).|
Knowledge of its national distribution in Europe is as follows:
Native:Belgium; Bulgaria; Denmark; France (France (mainland)); Germany; Greece (Greece (mainland)); Ireland; Italy (Italy (mainland), Sicilia); Luxembourg; Macedonia, the former Yugoslav Republic of; Malta; Netherlands; Poland; Portugal (Madeira, Portugal (mainland)); Slovenia; Spain (Spain (mainland)); Sweden; Switzerland; Ukraine (Krym); United Kingdom (Great Britain)
|Population:||Knowledge of the European population at national level is as follows:|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||In Germany, this species grows in coastal salt meadows, pastures and grasslands (Bundesamt für Naturschutz 2010). In the UK, this lowland species grows in meadows and pastures, along roadsides and in river valley floodplains—it prefers sticky, clay soils (Preston et al. 2002). At the coast it is often found in grazing marsh grasslands and on earthen sea walls (Preston et al. 2002). In the Netherlands, it grows in brackish wet soils and in humid and very fertile soils (Tamis et al. 2003).|
|Use and Trade:||H. secalinum is a tertiary wild relative of and potential gene donor to barley, H. vulgare.|
Further research is needed to gather information about the potential threats to this species.
The genus Hordeum is listed in Annex I of the International Treaty on Plant Genetic Resources for Food and Agriculture.
H. secalinum is listed as Least Concern in Denmark (Den Danske Rødliste 2010). It is not threatened in the Netherlands.
In Germany, it is evaluated as endangered (Red List category 3) but it is not protected (Bundesamt für Naturschutz 2010). In France, it is protected in the region of Alsace (Association Tela Botanica 2000–2010).
EURISCO reports 23 germplasm accessions of H. secalinum held in European genebanks, 20 of which are reported to be of wild or weedy origin. Of the wild accessions, 18 originate from within Europe (EURISCO Catalogue 2010).
